What do the results mean?
If your results show low or normal D-dimer levels in the blood, it means you probably don’t have a clotting disorder.
If your results show higher than normal levels of D-dimer, it may mean you have a clotting disorder. But it cannot show where the clot is located or what type of clotting disorder you have. Also, high D-dimer levels are not always caused by clotting problems. Other conditions that can cause high D-dimer levels include pregnancy, heart disease, and recent surgery. If your D-dimer results were not normal, your provider will probably order more tests to make a diagnosis.
If you have questions about your results, talk to your health care provider.
